Facebook (non-)Insights

I can easily get insight into who tweeted
it. But Facebook
is a big black box. In theory, I can use Facebook
Insights to track this. It claims
that 50 actions have led to ~2400 visits to my site, but declines to say anything more:

I understand that Facebook is more private than Twitter, but this is
frustrating. I’d hope to at least see which country the shares are happening
in. Are these French people coming to Comparea? Australians? Facebook won’t
even reveal that all the recent visits are to a single URL! I’d think that
thousands of clicks would be enough to provide anonymity there.

I’m not sure exactly what sorts of insights Facebook can share without
revealing identities, but I’d very much hoped for more than this.
